HARRY THOMAS MUMFORD, F NEW' YORK, N. Y., ASSIGNOR TO MUMFORD MANU-FACTURING AND SUPPLY COMPANY, A CORPQRATION OF NEW YORK.

BELT-LACING TOOL AND SQUARE.-

To all whom it may concern:

Be it known that I, HARRY T. MUMFORD, a subject of the King of England,and a resident of New York, county and State of New York, have inventedcertain new and useful improvements in Belt-Lacing Tools and Squares, ofwhich the following is a full, clear, and exact description.

This invention relates more particularly to a tool adapted for squaringthe ends or parts of belting and to form a metallic lacing at each endthereof.

rllhe primary object of the invention is to provide a simple andefficient tool or device which may be cheaply made and'which is adaptedto be placed and held to the end of the belt to be laced in such a wayas to form a guide for the wire employed as a lacing, and which lacingis formed as spiral so as to adapt the saine to be interlocked and heldto a similar lacing formed in the same way lon the other end of thebelt.

A further object of the invention is to provide a device which may beemployed as a square to straighten the edge properly for the lacing orfor other purposes; which may be made out of sheet metal, and which isadapted to lio-ld the lacing` properly until it is formed into therequired'shape.

lith these and other objects in view, the invention .will be hereinaftermore particularly described with reference to the accompanyingdrawinc's, which 'form a part ot this specification, and will then bepointed out in the claims at the end of the description.

In the drawings, Figure 1 is a fragmentary plan view of the tool beforethe same is applied to the belt. Fig. 2 is an end view of the tool. Fig.3 is a plan view showing how the tool is used to torni the lacing. Fig.Ll is a longitudinal section through the tool while forming the lacingas shown in Fig. 3. Fig. 5 is an enlarged fragmentary side elevation ofthe tool. Fig. 6 is a detail view of one end of a belt after the lacinghas been formed; and Fig. 7 is a plan view of the tool complete.

The tool 10 may have a body portion 11 at one end of which is Jformed ahead 12 and an extended portion 13 along the edge ot which may beprovided graduations so as to adapt the same as a scale for measuringpurposes. rllhe body portion 11 may comprise two sheet metal members 14and 15 Spec'caton of Letters Patent.

which may be riveted together, or the said body portion may be cast orotherwise made as desired.

At the upper edge of the head 12 may be arranged a plurality of slots orgrooves 16 and these grooves project inward and are angularly disposedwith respect to the outer edge 17 of the head. The outer end of the headis provided with teeth 18 formed by the grooves or slots 18 and theseteeth at the upper ends of the member le are bent in one direction whilethe teeth of the member are bent in the opposite direction, and saidteeth are substantially L-shaped and so arranged that when the membersare jointed together by riveting 0r otherwise, as at 19, along thesurface thereof, the said teeth of the members will be opposed and thegrooves or slots 16 in alinement with each other, the inner edge 2O ofthe teeth being made so as to lie at right angles to the edge 21 of theextension 13 and forming a transverse abutting surface, thus permittingthe tool or device to square the ends of the belt by placing theabutting surface against the edge of the belt so that the edge 21 willextend transversely or across the belt, or permitting the device to beused for other purposes.

To support a former or mandrel while lacing the end of the belt Iprovide two eX- tended portions 22 and 23 on each member, and each oisaid portions is bent or formed so as to provide eyes 232L on the member14 and eyes 23b on the member 15, said eyes being arranged on oppositesides of the members, in which a mandrel 24 or other device may beinserted as shown in Figs. 3 and 4t, to properly form the body of thelacing and also to space the same a proper distance from the edge of thebelt.

When the tool is used, it is removably fastened to the end ot the belt25 by rivets 26 or otherwise, and the mandrel or former 24 Y is slippedthrough the eyes of one of the members, as the eyes 23". A plurality ofholes 27 are formed in the end of the belt by an awl or other device atthe inner end of each groove or slot 16, the edges of the teeth and theend of the slot serving as a guide for properly positioning the holes.The lacing wire is fastened at one end to the edge of the belt as shownin Fig. 4 and is then bent over the mandrel and threaded through one ofthe openings or holes 27 using the slots and teeth as a guide, land thenpulling the wire so as to make the same very tight after which the wireis again threaded through the next opening and continued throughout theentire width of the belt. rEhe mandrel 24 may now be removed and thetool removed from the end of the belt leaving the lacing formed in aspiral manner as shown in Fig. 6. The opposite end of the belt islikewise laced by means of the tool and when the lacing has been formedin the two ends of the belt t-hey are brought together so that thelacing of one end will fit into the other and by inserting a rod ordevice through the opening formed between the laced members the saidbelt will be properly held together in the usual manner.

While the invention is shown as made of sheet metal it is to beunderstood that it may be cast or otherwise made of any suitablematerial, that the body portion thereot may be formed in any desired wayand of any desired shape, and that the slots or grooves in the endserving as a guide for the belt lacing may be arranged in any desiredway and the inner end of the grooves made round to better guide the awlor tool in making the holes for the lacing if desired.

From the foregoing it will be seen that a simple and eliicient device isprovided whereby the usual form of wire lacing for the end of belts maybe quickly formed; that said tool is simple in construction andinexpensive to manufacture; and that the said tool may be utilized as asquare for trimming the ends of the belt or for other purposes.

Having thus described my invention, l claim as new7 and desire to secureby Letters Patent l. A tool of the character described, having its bodyportion provided with a plurality of obliquely disposed teeth projectingtherefrom and forming obliquely disposed slots extending into said bodyportion lengthwise thereof to form angularly disposed lacing.

2. A tool of the character described, having its body portion providedwith slots obliquely disposed with relation to the laeing end of thetool to cause the lacing to assume a spiral form.

3. A tool of the character described, having its body portion providedwith slots obliquely disposed with relation to the lacing end'of thetool to cause the lacing to assume a spiral form, and with teethprojecting on opposite sides of the body portion.

4. A tool of the character described, comprising a body portion having astraight edge at one sid-e thereof, and a plurality of substantiallyL-shaped teeth spaced apart and extending on opposite sides of the bodyportion and atl right angles to said edge.

5. A tool of the character described, comprising a body portion having astraight edge at one side thereof, and a plurality ot' teeth extendingoutward from opposite sides of the body portion and at right angles tosaid edge and spaced apart so as to provide angularly disposed groovesbetween said teeth.

5. A tool of the character described, comprising' a body portion havinga straight outer edge, a plurality of teeth having grooves between thesame and extending angularly with respect to said edge and on oppositesides of the body portion to form guides for lacing a belt, and eyeslocated on arch side of the teeth adapted to hold a inandrel aroundwhich the lacing' may be formed.

7. A tool of the character described, comY prising a body portion havinga plurality of angularly disposed teeth spaced apart to provide groovesbetween the same, and eyes located on each side of the teeth adapted tohold a mandrel around which the lacing` may be formed.

8. A tool of the character described, comprising a body portion having astraight outer edge, a plurality of teeth having grooves between thesame projecting from the body portion to form guides for lacing a belt,and eyes located on each side of the teeth adapted to hold a mandrelaround which the lacing may be formed.
